א אֵין מַרְגִּילִין בְּיוֹם טוֹב, כֵּיצַד הוּא מַרְגִּיל, זֶה הַמּוֹצִיא כָּל הַבָּשָׂר מֵרֶגֶל אֶחָד כְּדֵי שֶׁיּוֹצִיא כָּל הָעוֹר שָׁלֵם וְלֹא יִקְרַע, מִפְּנֵי שֶׁטּוֹרֵחַ בְּהֶפְשֵׁט זֶה טֹרַח גָּדוֹל וְאֵין בּוֹ צֹרֶךְ לַמּוֹעֵד.
1 Laws of salting and removing feathers on Yom Tov. Containing 5 paragraphs: One does not defeather using the margil method on Yom Tov. What is this margil method? It is when one removes all the flesh from one leg in order to remove the entire hide intact without it tearing because the effort of this skinning is a great effort, and there is no need for it on the festival.
ב אָסוּר לִמְלֹג גְּדִי אֶלָּא אִם כֵּן מוֹלְגוֹ לֶאֱכֹל הָעוֹר.
2 It is forbidden to boil a kid unless you boil it to eat the skin.
ג בְּהֵמָה שֶׁנִּשְׁחֲטָה בְּיוֹם טוֹב, מֻתָּר לְהַגְבִּיהַּ עוֹרָהּ וְלִתְּנָהּ בִּמְקוֹם דְּרִיסַת הָרַגְלַיִם, אַף עַל פִּי שֶׁאֵין עָלָיו בָּשָׂר כְּלָל. וּמֻתָּר לִמְלֹחַ עָלָיו מְלִיחָה קַלָּה כְּדֶרֶךְ שֶׁמּוֹלְחִים לַצָּלִי. וּמֻתָּר לְהַעֲרִים לִמְלֹח כָּאן מְעַט וְכָאן מְעַט, עַד שֶׁיִּמְלַח אֶת כֻּלּוֹ. אֲבָל אִם נִשְׁחֲטָה מֵעֶרֶב יוֹם טוֹב, אָסוּר. הַגָּה: וְנוֹצוֹת שֶׁל עוֹף דִּינָן כְּמוֹ בְּעוֹר דְּמֻתָּר לְטַלְטְלָן כְּדֵי לְהַצְנִיעָן, כְּמוֹ בְּעוֹר.
3 Regarding an animal that was slaughtered on Yom Tov, it is permissible to remove its skin and put it in an area of foot traffic even though there is no meat on it, and it is permissible to salt it lightly like the way we salt for roasting, and it is permissible to trick (by leaving bits of meat) and salt here and there until you salt the whole thing, but if it was slaughtered before Yom Tov it is forbidden. Rema: and feathers of birds their rule is like that of skin, that you are allowed to move them to save them, like skin.
ד אֵין מוֹלְחִין אֶת הַחֲלָבִים וְלֹא מְהַפְּכִים בָּהֶם, אֲפִלּוּ לְשָׁטְחָן עַל גַּבֵּי יְתֵדוֹת, אַף עַל פִּי שֶׁנִּשְׁחֲטָה בְּיוֹם טוֹב; וְכֵן אָסוּר לִמְלֹחַ בָּשָׂר עֲלֵיהֶם בַּאֲוִיר.
4 One may not salt fats on Yom Tov or flip them, or even to put then on stakes, even if it was slaughtered on Yom tov, it is also forbidden to salt meat over them in the air.
ה עֵלִי, שֶׁהוּא דַּף עָב וְכָבֵד וּכְלִי הוּא, אֶלָּא שֶׁמְּלַאכְתּוֹ לְאִסוּר לִכְתֹּשׁ בּוֹ הָרִיפוֹת, מֻתָּר לְטַלְטְלוֹ לִקְצֹב עָלָיו בָּשָׂר; וּלְאַחַר שֶׁקָּצַב עָלָיו אָסוּר לְטַלְטְלוֹ מֵחַמָּה לַצֵּל, אֲבָל לְצֹרֶךְ גּוּפוֹ וּמְקוֹמוֹ שָׁרֵי.
5 A pestle that is thick and heavy is considered a vessel, but its designated use is for a prohibited purpose—to crush herbs with it. It is permitted to move it in order to cut meat upon it. But after one has cut upon it, it is forbidden to move it from sun to shade. [However, for its own sake or for the sake of its place, it is permitted.]
